Tomas Tyml


Global Viral

Postgraduate Research: Masaryk University Brno, Czech Republic

Ph.D. (Parasitology), University of South Bohemia, Czech Republic

Research focus: Protistology, Microbial symbiosis, Parasitology

Other appointments: Visiting Scientist, Joint Genome Institute

Tomas joins Global Viral (GV) as a Fellow working on the Boundaries of Life project in collaboration with the Joint Genome Institute (DOE’s Lawrence Berkeley National Laboratories). He is interested in protists, eukaryotic microorganisms, and particularly on free-living amoeboid protists (FLA) and scattered in several major eukaryotic groups. Currently, he is very interested in enthralled in protist-associated bacteria and viruses and studying interactions between them and their hosts via culturing approach and using cutting-edge methods.

While working on his graduate education, Tomas joined the Institute of Parasitology (Czech Academy of Sciences) involving in a series of research projects under the guidance of professor Iva Dykova. Tomas has worked in the fields of protistology and parasitology ever since. He received his PhD in parasitology from the University of South Bohemia (USB) in the Czech Republic focusing on a diversity of FLA. Before he joined GV, Tomas had continued his studies on FLA at Masaryk University in Brno (Czech Republic) but also on protistan parasites of fish as a member of several expeditions to the High Arctic organised by the Centre for Polar Ecology at USB.


Tomas is proficient in a wide range of techniques, including culturing of various groups of protists and cell lines, staining and other light microscopy-based morphological methods, molecular taxonomy and diagnostics, routine methods of parasitology and transmission electron microscopy.
